MAGAZINE FOB PI-IONOGRAPH NEEDLES.

Applicationl filed .Tune 15, 1922. Serial No. 568,399.

T all 'whom t may concern Be it known that we, CHARLES 0. Fon- DrsoH and ROY J. FonnrsoH,both citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Im- Y provements in Magazines for Phonograph Needles, of which the following is a full, clear, and exact description.

The invention relates to magazines for phonograph needles. In handling loose needles, it frequently occurs that the `sharp points prick the ngers used to grasp the needle while placing it in the needle socket of the reproducer; that the needle points are frequently injured when kept loosely in a compartment; and that the needle points become rusted from dampness in the atmosphere.

The object of the invention is to provide a simple magazine for a supply of needles which will protect their points against injury, avoid all danger of pricking the lingers when they are grasped and will prevent the points from corroding.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a side elevation of a magazine embodying the invention, one side thereof being partly broken away. Fig. 2 is a section on an enlarged scale taken on line 2-2 of Fig. l. Fig. 3 is a detail of one of the disks forming one side of the magazine. Fig. 4L is a view, partly in elevation and partly in section of a modified form of the invention. Fig. 5 is a section taken on line 5-5 of Fig. 4. Fig. 6 is an end view of the modilication shown in Fig. 4. Fig. 7 is a section taken on line 7-7 of Fig.

In Figs. 1 to 3, the invention is exemplied in a magazine which is circular in form and is adapted to receive and retain in its marginal portion a series of phonograph needles in spaced relation so that they may be individually grasped and so that the Shanks will project therefrom. The magazine comprises a pair of sheet metal circular disks 10 which are secured together by struck-up tongues 11 which are adapted to pass through slots 11a and clinched to secure the two disks together. rIhe central portion of the disks are abutting and their marginal portions are bent outwardly, as at 12, so they will be spaced apart sufliciently for retention of the needles. A rubber ring or washer 13 is held between the inner portions 1:2 of the disk. strip of cotton wick 14 saturated with paralline or oil extends around and is disposed outwardly of the rubber cushion 13. An annular spring or coil of wire 15 extends around the strip 14 and the ends ot this spring are hooked together in such manner that the wire will be under slight tension while it is in the magazine. The outer margins of the disks are turned inwardly and slightly at 16 to hold the spring in place be* tween the disks. The needles 17 pass he tween the coils of spring 15 through the lu- 70 bricated wick liand into the cushion 13, so that they will be firmly held in the magazine until it is desired to withdraw them for use. The spring forms a convenient spacing means for the needles and also serves to frictionally hold them outwardly of their points which are held in the cushion 13.

In the exempliiication of the invention shown in Figs. 4L to 7, the body of the magazine is made of a strip of sheet metal bent to form two arcuate sides 20, an integral connecting strip 21 and end closures 22. A strip of rubber 13a forms the cushion for the needle points. Lubricated wick 11i-a is disposed contiguous to the outer surface of the cushion and a spring 152L having its ends hooked to struck-up tongues 23 on the ends 22 is adapted to space the needles and hold them outwardly of the cushion. The outer margins of the sides 2O are bent inwardly, as at 24:, to retain the spring in the holder.

The invention exemplifies a magazine which is adapted to receive a series of phonograph needles and hold them in spaced relation with their Shanks projecting from the margin thereof, so they may be conveniently grasped and inserted into the needle socket without handling the needle points with the lingers. rlhe spring serves as a spacing and gripping means for the needles which is inexpensive and may be easily placed in operative position in the holder. The lubricated wick causes the needle point to he lubricated when it is inserted and withdrawn so that the point will be protected from corrosion. The device as an entity may be produced at a low cost.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the apceive a series of phonograph needles, and a Wire coil to frictionally engage the needles and space them in the holder.

2. In a device of the character described, the combination of a holder adapted to receive a series of phonograph needles, a wire coil to space and frictionally retain the needles, and a cushion for the needle points disposed inwardly or' the coil,

3. In a device of the character described, the combination of a holder formed or a pair of' disks and adapted to receive a series of phonograph needles, and an annular coil spring to JErictionally retain the needles in the holder.

4. In a device of the character described, the combination of a holder adapted to receive a series of phonograph needles, means to retain the needles in the holder, and means provided with a lubricant for the needle points.

5. In a device of the character described, the combinationof a holder adapted to receive a series of phonograph needles, a cushion in the holder for the needle points, and a strip provided with a lubricant to apply it to the needle points upon insertion and removal from the cushion.

6. In a device of the character described, the combination of a holder adapted to re ceive a series of phonograph needles, a cushionin the holder for the needle points, a strip provided with a. lubricant to apply it 'to the needle points upon insertion and removal from the cushion, and means for holdineF the needles outwardly of the strip.

ligned at Chicago, Illinois this 6th day of June, 1922.
